A bot is simply a piece of software that automates simple tasks, like ordering food. Chatbots are a type of bot that live in messaging apps (like Facebook Messenger) and use artificial intelligence to perform tasks via simulated conversation. These exchanges typically include a series of options presented by the bot. In a nutshell, chatbots facilitate “choose your own adventure” style interactions.

In a blog post about F8 2016 announcements, Facebook explained bots for Messenger: “As part of the new Messenger Platform, bots can provide anything from automated subscription content like weather and traffic updates, to customized communications like receipts, shipping notifications, and live automated messages—all by interacting directly with the people who want to get them. The Messenger Send/Receive API will support not only sending and receiving text, but also images and interactive rich bubbles containing multiple calls-to-action.”

Why will people use chatbots?

Because they’re already using Facebook Messenger

Facebook’s new chatbots do something for users that regular apps don’t: they reach them where they already are. A user simply has to type the name of a bot they want to use into the Facebook Messenger search bar and open a chat window. This is a far lower barrier to use than having users find and download an app from the app store.

The Facebook Developer blog explained that the new Messenger Platform would provide: “Expanded access to the Messenger platform by giving you the ability to reach your customers where they already are with a new send and receive API. You will be able to build a custom bot in Messenger, providing anything from customer service to rich, interactive experiences such as automated responses or spawning a search.”

Every month, 1 billion messages are sent between people on Messenger and Businesses and Pages. Chatbots simplify that process. The potential uses for brands are immense.

Chatbots are easy to find and use

Plus, Facebook aims to solve the issue of discovery that plagued the app ecosystem by “piggybacking onto the existing user flows of the mobile web.” Fast Company’s Cliff Kuang predicts that chatbots could become the new Like button: “There will be new plugins that companies can add to their websites, which will fire up their chatbots in Messenger. There will also be codes that business can slap onto stickers in their real life spaces—much like Kik does—which will allow patrons to fire up chatbots on the spot. Both Facebook Newsfeed and SMS messages will now have a prompt letting you continue a thread inside of Messenger.”

Bot responses should be “paced quickly, but not so quickly that the bot is oppressively present—like a chat partner hanging on your every word and expecting just as quick of a response.”

And it’ll only improve with time. (At least, that’s the plan.)

David Marcus, vice president of messaging products at Facebook, explained to Fast Company that the AI will get better as the bots absorb data about the things people say and the questions they ask. Fast Company wrote: “Over time, according to Marcus, this mix of natural language chat and tappable bubbles will yield a chatbot UX that feels increasingly fluid and intuitive.”
